Cyclic/Collective Pitch Mixing — Aileron, Elevator, and Collective are combined to give helicopter swash plate servo commands. Required for control of most modern RC helicopters that use a flybar. See also CPPM.
Heli Setup
A term used by RC helicopter pilots describing rapid reduction of throttle stick setting on the Tx. A habit often formed with fixed pitch or coaxial helicopters that can destroy fixed pitch helicopters by driving them into the ground
A type of helicopter with two sets of counter rotating main blades. Typically both sets of blades have set pitch angles.
Collective Pitch Direction. Specifies the direction, Normal (—) or Inverse (INV).
Collective is the angle of the main rotor blades of a heli and is why a collecive pitch helicopter can fly upside down. Helicopters with fixed pitch blades (this includes almost all coaxial helicopters) do not require collective.
A helicopter that has main blades that can change angle while in flight. Usually achieved by adjusting the tilt and height of a swash plate.
Specifies the virtual channel to be used on MIXER page for pitch curve(s).
Combined Pulse Position Modulation — Allows two functions (cyclic and collective pitch mixing) to drive three servos for the swash plate of a helicopter. See also CCPM.
CYC1, CYC2, CYC3 describe the OpenTX outputs for CCPM mixing for direct control of servos on the swash plate of a helicopter. Inputs are Aileron, Elevator, and Collective.
A helicopter term describing the combination of aileron and elevator.
